Hi,
-- As per knowledge no need to follow the ASME B31.3 IN this case, check and confirm the fit-up in line if fabricated in shop or in field.
Second monitor the joint weld after and during the welding process of two pipes or spools .
Third one , check the straightness of pipe before welding.(solution make straight)
fourth one , check structure alignment is correct or not.(if concrete beam advised to make level )
finally try to put seam to maintain the level .
But After reading your question i am on conclusion that check support weld and welding process .
Thank you.

I wanted to know what is the acceptance criteria for the straightness if the line pipe.Please provide the reference.
